#include <Servo.h>

//Servo servo1;

const int flexpin = 0;


void setup()
{

  Serial.begin(9600);

  //servo1.attach(9);
}


void loop()
{
  int flexposition;    // Input value from the analog pin.
  int servoposition;   // Output value to the servo.

  // Read the position of the flex sensor (0 to 1023):

  flexposition = analogRead(flexpin);

  // Because the voltage divider circuit only returns a portion
  // of the 0-1023 range of analogRead(), we'll map() that range
  // to the servo's range of 0 to 180 degrees. The flex sensors
  // we use are usually in the 600-900 range:

  //servoposition = map(flexposition, 600, 900, 0, 180);
  //servoposition = constrain(servoposition, 0, 180);

  // Now we'll command the servo to move to that position:

  //servo1.write(servoposition);

  // Because every flex sensor has a slightly different resistance,
  // the 600-900 range may not exactly cover the flex sensor's
  // output. To help tune our program, we'll use the serial port to
  // print out our values to the serial monitor window:

  Serial.print("sensor: ");
  Serial.print(flexposition);
  //Serial.print("  servo: ");
  //Serial.println(servoposition);

  // Note that all of the above lines are "print" except for the
  // last line which is "println". This puts everything on the
  // same line, then sends a final carriage return to move to
  // the next line.

  delay(20);  // wait 20ms between servo updates
